A few weeks ago, I tested our 2014 SLP Panther Camaro to determine just how loud it was in a tunnel. This week, I decided to use the same decibel-meter apps and the same tunnels to repeat the test with our long-term 2014 Chevrolet Corvette Stingray. Ya know, for science n' stuff.

So which was louder?

Before I went blasting through tunnels though, I needed to look at the official numbers. When Edmunds.com tests cars, we measure interior sound levels. With the climate control and stereo turned off and the windows rolled up, we take three measurements: one at idle, one at full throttle and one at 70 mph. Here are the testing results from our Stingray (in both Touring and Sport modes) along with a few sixth-gen Corvettes, the SLP Camaro, and the two quietest cars currently in our long-term fleet: the 2014 Ram 1500 and 2013 Tesla Model S.

My test was not official.

Between Turn 5 and Turn 6 at Laguna Seca, the Stingray registered 96 decibels and was politely asked to keep it down. In a tunnel at full throttle, with the windows down, the Stingray registered at least 100 dB, the same as the SLP. Many sources say that 100 dBs is the iPhone's measurement limit, so if things are any louder, it can't register the difference. For reference, many outdoor concerts are limited to 115 dB and hearing damage can occur with prolonged exposure to anything measuring over 85 dB. So even if this app is capped, we're still in the hearing-damage zone. At least in this tunnel. Is the spine-tingling rumble of the Stingray's V8 worth it? Absolutely.
